standardized and reliable in vitro screening methods. The lack of standardized methods also makes direct comparison of results between studies impossible. The various methods used are disc diffusion, well diffusion, agar dilution and broth dilution. Both the diffusion and dilution methods have been widely used for many years to accurately
Dilutions: Explanations and Examples of Common Methods. There are many ways of expressing concentrations and dilution. The following is a brief explanation of some ways of calculating dilutions that are common in biological science and often used at Quansys Biosciences.
Broth Dilution We can test how sensitive and, by extension resistant, bacteria are to antibiotics via numerous ways. One of them is known as the Broth dilution method .
by serial dilution before the sample is spread on the surface of an agar plate. 1. Prepare serial dilutions of the broth culture as shown below. Be sure to mix the nutrient broth tubes before each serial transfer. Transfer 0.1 ml of the final three dilutions (10-5, 10-6, 10-7) to each of three nutrient agar plates, and label the plates. 2.
